Show HN: An open-source rhythm dungeon crawler in 16 x 9 pixels I just released my latest Godot project, a rhythm-based dungeon crawler a la Crypt of the Necrodancer. The entire game plays out in 16 x 9 pixels because of a dare from my game dev group. I've open-sourced (MIT) the code and project files. Of course, the music files I don't own aren't included in the Github project, but I'm releasing the game's hand-crafted pixel sprites under CC0. The Github page also talks about some of the tricks you need to make the rhythm part of the game play nice with the dungeon crawling part. https://ift.tt/8nH57up June 6, 2025 at 03:50PM

Show HN: RenderDay: A GPU-only render farm for Blender https://ift.tt/FMWwCg6

Show HN: RenderDay: A GPU-only render farm for Blender Hey HN! I recently had to render my first longer Blender animation, and I found myself pretty frustrated with the existing render farms out there. Everything I tried was either buggy, overly complicated (I really don’t want to pick from a huge list of hardware options), or just *really* expensive. So, I did what anyone would do.. I built my own solution: https://renderday.com - a GPU-only render farm for Blender that’s super fast and dead simple to use. You just: 1. Upload your `.blend` file 2. Pick your settings 3. Get a price, pay, and render - done No subscriptions, no upfront costs, no contracts - just pay as you go. I pull in daily GPU prices from multiple providers (with a tiny margin to keep the lights on), so the pricing is transparent and competitive. Under the hood it's running on NVIDIA L40S GPUs (48GB RAM), with access to over 1,000 GPUs globally. Currently supports: * Blender 4.3 and 4.4 (can add more if needed) * Cycles and EEVEE * Real-time progress tracking with live preview frames * Full file encryption, auto-deletion after 30 days, no access/sharing --- But more importantly: I'd really appreciate your feedback. This started as a personal itch, but I want to build something genuinely useful for the Blender community - especially indie creators and small studios who can't afford big monthly plans or don't want to deal with complicated setup. - What do you wish render farms did better? - What features are missing for you right now? - Would you use something like this - and if not, why not? Would love to hear your thoughts - good or bad - so I can keep improving it. Thanks for reading! Sascha https://renderday.com June 10, 2025 at 02:24AM

Show HN: I made a mobile app that turns your step count into a race https://ift.tt/Q7ORJhm

Show HN: I made a mobile app that turns your step count into a race I just launched my first-ever mobile app. It’s called STEPRACERS, a game where you compete with friends by tracking your steps. The idea came from someone close to me who completely changed their life by focusing on their health. Every night, they’d send me their step count - a small, daily ritual that became a powerful reminder of progress. So I turned it into a game. It’s fun. It’s simple. And it might just push you to hit your 10k steps a day. https://ift.tt/eA31jvC June 10, 2025 at 02:28AM

Show HN: AI that extracts brand identity from websites to generate ads https://ift.tt/Tm6LerB

Show HN: AI that extracts brand identity from websites to generate ads I built this because I kept procrastinating on creating ads for my projects. The technical challenge was interesting: how do you teach AI to extract "brand identity" from a website? Turns out websites are messy. Finding the actual logo vs random images, identifying brand colors vs generic link colors, understanding brand voice from homepage copy. The solution: Custom vision models + CSS parsing + GPT-4 for voice analysis. You paste a URL, it extracts brand elements, generates platform-specific ads. Not trying to "disrupt advertising" or anything dramatic. Just solving the specific problem of "I need a Facebook ad but Canva makes me want to cry." Built with Next.js, custom image processing pipeline, OpenAI API. The brand extraction accuracy is around 85% for well-structured sites, lower for sites that are... creative with their CSS. Happy to discuss the technical approach or share code snippets if anyone's curious about the brand extraction pipeline. https://board.ad https://www.board.ad June 8, 2025 at 10:45AM

Show HN: AI game animation sprite generator https://ift.tt/WQYnhAE

Show HN: AI game animation sprite generator I tried to build AI game animation generator last year ( https://ift.tt/VCIAUnG ), a lot of people were interested, but it failed, mainly because the technology was not good enough. 1 year passed, there were a lot of developments in video/image generation. I tried it again, I think it works super well now. Actually beyond my expectation. You can generate all kinds of game character animation sprites with only 1 image. 1, upload your image of your character 2, choose the action you want 3, generate! Support basic actions like Run, Jump, Punch and complicated ones like: Shoryuken, Spinning kick, etc. High quality sprite sheet will be directly generated to use in Unity and any game engine. If you are an indie game developer, you don't need to high an artist or animator to develop you game. For studios, it's 10x cost saving and 10x efficiency as no more creating animations for 100 NPCs 100 times. Please check it out, looking forward to your feedback! https://ift.tt/P5VeI38 June 7, 2025 at 01:00AM

Show HN: Lightweight Durable Workflows Built on Postgres https://ift.tt/yzbElje

Show HN: Lightweight Durable Workflows Built on Postgres Hi HN! This is Qian here with Peter (KraftyOne) and Jeremy (jedberg). We’re building DBOS, an open-source, lightweight durable workflows library that you can add to Python apps in just a few lines of code. It’s comparable to popular open-source workflow and queue libraries like Airflow and Celery, but more lightweight with a greater focus on reliability and automatically recovering from failures. Our goal in building DBOS is to make workflows lightweight and flexible so you can add them to your existing apps with minimal work. Everything you need to run durable workflows and queues is contained in this Python library. You don’t need to manage a separate workflow server: just install the library, connect it to a Postgres database (to store workflow/queue state) and you’re good to go. DBOS workflows make your program durable by checkpointing its state in Postgres. If your program ever fails, when it restarts all your workflows will automatically resume from the last completed step. You add durable workflows to your existing program by annotating ordinary functions as workflows and steps: from dbos import DBOS @DBOS.step() def step_one(): ... @DBOS.step() def step_two(): ... @DBOS.workflow() def workflow(): step_one() step_two() The workflow is just an ordinary Python function. You can call it any way you like–from a FastAPI handler, in response to events, wherever you’d normally call a function. We’ve just released DBOS Python 1.0. This enhances workflows with many powerful features we’ve been building over the last few months, including: - Durable queues. Postgres-backed queues with all the queuing features of BullMQ/Celery (concurrency limits, rate limits, timeouts, priority, deduplication, etc.). Plus, they integrate with durable workflows, so you can write a workflow that enqueues 1K tasks, waits for and processes their results, and automatically recovers from any interruption. - Programmatic workflow management. Your workflows are stored as rows in a Postgres table, so you have full programmatic control over them. Write scripts to query workflow executions, batch pause or resume workflows, or even restart failed workflows from a specific step. This makes it much easier to diagnose and recover from bugs and failures that affect thousands of workflows. - Full support for both sync and async Python–write your workflows and steps as code either synchronously or asynchronously, it all works out of the box. - Improved tooling, including dashboards, workflow graph visualization, workflow management via web UI, and more. We’d love to hear your feedback and hope you can try DBOS out! https://ift.tt/KHtu8Uj June 6, 2025 at 10:39PM

Show HN: Create LLM graders and run evals in JavaScript with one file https://ift.tt/0knyjTt

Show HN: Create LLM graders and run evals in JavaScript with one file Hi HN! Run it: OPENROUTER_API_KEY="sk" npx bff-eval --demo We built a tool to help people take LLM outputs and easily grade them / eval them to know how good an assistant response is. We've built a number of LLM apps, and while we could ship decent tech demos, we were disappointed with how they'd perform over time. We worked with a few companies who had the same problem, and found out scientifically building prompts and evals is far from a solved problem... writing these things feels more like directing a play than coding. Inspired by Anthropic's constitutional ai concepts, and amazing software like DSPy, we're setting out to make fine tuning prompts, not models, the default approach to improving quality using actual metrics and structured debugging techniques. Our approach is pretty simple: you feed it a JSONL file with inputs and outputs, pick the models you want to test against (via OpenRouter), and then use an LLM-as-grader file in JS that figures out how well your outputs match the original queries. If you're starting from scratch, we've found TDD is a great approach to prompt creation... start by asking an LLM to generate synthetic data, then you be the first judge creating scores, then create a grader and continue to refine it till its scores match your ground truth scores. If you’re building LLM apps and care about reliability, I hope this will be useful! Would love any feedback. The team and I are lurking here all day and happy to chat. Or hit me up directly on Whatsapp: +1 (646) 670-1291 We have a lot bigger plans long-term, but we wanted to start with this simple (and hopefully useful!) tool.

Show HN: Smart Palette – Reimagining AI Art https://ift.tt/HPtOhFQ

Show HN: Smart Palette – Reimagining AI Art Hi HN, I'm Nick. Over the last 6 months I’ve been building Smart Palette – a platform to help anyone create unique, wall-ready art without needing to be a prompt expert. I started this because I wanted to unleash creativity in anyone and help them bring their art ideas onto their wall through a simple, guided and inspiring process. Instead of figuring out the “right” words to use, you just select your interior design style, room, art style, theme, and color palette. You can simply describe what you want to see and add your desired colors — or let Smart Palette handle it for you. Smart Palette uses a streamlined UI that my backend then translates into optimized, detailed prompts. A lot of the work went into this "translation" layer to ensure optimal model selection, settings and generation techniques depending on the user’s creative context. It also has a full print-on-demand (UHD) integration including various cusotmization options and an art preview feature. This is an early version, and I'd be very grateful for any feedback you have on the concept, the UX, or any technical aspects. Happy to answer any questions! You can try it out with a free trial and generate your first artwork. Here’s a quick walkthrough: https://ift.tt/k1xzdOK?... https://ift.tt/kG1A2jo June 5, 2025 at 12:58AM

These are deliberately non-functional, weird, sometimes funny, sometimes philosophical — and usually totally unnecessary. Some examples: Sexy Math — solve math problems to reveal erotic images. Trip to Mars — a real-time simulation that takes 7 months to finish. Add Luck to Your e-Store — add a waving cat widget to boost your conversion via superstition. Microtasks for Meatbags — the future: AI gives prompts, humans execute. Invisible Lingerie — it’s sexy. And invisible. Artist Death Tracker — art prices spike when artists die. We track that. Open Celebrity — one open-source face, shared by all. Together we make her famous. I just enjoy exploring what the web can be when it doesn’t try to be “useful”. Would love to hear what you think — and absurd ideas are always welcome. https://absurd.website June 3, 2025 at 01:22AM

Show HN: GoogLLM – Google search that returns Markdown instead of HTML https://ift.tt/Y2NJZ3e

Show HN: GoogLLM – Google search that returns Markdown instead of HTML As part of my bigger goal to make the web more agent-friendly, this weekend i decided to tackle google. The "AI-native" search APIs like Tavily and Exa exist, but they require setup and don't actually use Google's results. So I built something simple - a proxy that takes Google search URLs and returns the results as clean markdown instead of HTML. You literally just change "google.com" to "googllm.com" in any search URL. ```bash # Returns 500KB of HTML: curl " https://ift.tt/9mkJwB0 " # Returns clean markdown: curl " https://ift.tt/K7pD4ei " ``` *What it does:* - Serves normal HTML to browsers (so humans can use it normally) - Returns markdown to everything else (curl, fetch, LLM agents) - Supports all Google search types: web, images, news, scholar, shopping, etc. - No auth needed for testing (10 requests/hour free) *Technical approach:* - Content negotiation based on Accept headers - Caches results to avoid hammering Google - Simple pricing: 0.5¢ per search after free tier I built this over a long weekend because I was tired of writing HTML parsers for every project. The whole thing is designed around a single principle: make Google search results consumable by LLMs without any complexity. *Questions for HN:* - Is this approach too simplistic? Should search APIs be more complex? - How do you currently handle search in your LLM applications? - Any concerns about the proxy approach vs. building from scratch? The llms.txt documentation is intentionally comprehensive (2500 tokens) so any LLM can understand and use it immediately. Live demo: https://googllm.com API docs: https://ift.tt/UeHYpdo Would love feedback on the approach and any edge cases I might have missed. https://googllm.com June 3, 2025 at 12:37AM

Show HN: Changefly – Rebuilding the foundation of privacy and authentication https://ift.tt/qkZ4biR

Show HN: Changefly – Rebuilding the foundation of privacy and authentication Lukas here, founder of Changefly. For those of you who might remember neworder.box.sk and astalavista.box.sk, I was one of the admin's at a very young age. Fast forward to 2018, I set out to help people regain their privacy. Google invited us into the Google Cloud Startup program which led to the creation of Changefly. After years of truly challenging work and thousands of iterations, Changefly ID was born. Changefly ID solves the problem both users and companies face on a daily basis... spam, scams, bots, account takeover attacks. At face value it looks like an ordinary code, but in fact, it is an encrypted security code that only the user knows and has access to use (a distributed anonymous authentication code). Changefly ID has a lot of flexibility -- replace traditional authentication (which you absolutely should do) or use secondary for multi-factor authentication (a good stepping-stone). It also includes end-to-end communications with your users through Changefly (not email, sms, or other unsecured channels). Additionally, the Changefly app data is also end-to-end encrypted as is the local data. We made access to Changefly ID easy and free with our Developer API. Changefly ID really does stop bots, spam, scams, and other threats from getting anywhere near users or their accounts. p.s.

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard ) (All the sources on github under an open source license :D) PS.

Show HN: Clean Simple DNS Lookups https://ift.tt/j9R4Tws

Show HN: Clean Simple DNS Lookups Hey HN, Last weekend I vibe-coded a cool website that lets you do easy DNS record lookups. I know you can just use dig or nslookup, but oftentimes I'm too lazy to remember the syntax, and there are less technical users who need to manage DNS entries but aren't comfortable with the command line. We debug customer DNS issues often at ImprovMX, and we typically link to tools like mxtoolbox.com to point out DNS record issues. But those tools seem quite bloated and from the 2000s. I wanted something super clean & simple, and there were a few features I thought were ergonomically needed but lacking: - no confusing dropdowns or syntax for DNS lookup, just put in your domain or subdomain - click-to-copy for all values - header-links so we can provide URLs that will direct another user to an exact domain and which record we want to reference This was SUPER FUN to vibe code! The frontend was pretty much one-shotted with lovable. It's amazing how good AI is when working on a clean slate with all the latest popular frameworks (react, tailwind, shadcn, etc.). And I spent the next few hours making small tweaks with cursor. The backend is a dead simple python flask server. Both are hosted on render.com <3 I love how simple and value-oriented render.com is. It's always the provider that gives me the least headache when I want to just launch and forget something.

Show HN: Octogen: e-commerce capabilities for agents Hi HN, We just released a public beta of e-commerce capabilities for AI agents — aimed at developers building shopping agents or personal assistants. It’s early and buggy, but we’d love your feedback. Try a live demo here: https://ift.tt/A65DnU8 --- ## Why we built this We believe the biggest *technical* bottleneck in building consumer e-commerce agents is fragmented product data and inconsistent schemas across online stores. So we created a high-fidelity yet unified interface for *e-commerce catalog + checkout*, regardless of the underlying platform. --- ## What it does We currently offer two core capabilities: ### 1. Unified product catalog (for LLM-style search) - Octogen automatically wrangles any ecommerce site into a common schema — a superset of `schema.org/Product`. - It works across platforms and is available today for hundreds of sites. - You can request new stores — ~95% are processed fully autonomously. - Useful for agents doing RAG-based product search with rich attribute awareness. ### 2. Agentic checkout (closed beta) - Works on *any ecommerce site* using virtual cards (Visa only for now). - Enables agents to complete checkout flows much faster than browser-based "computer agents." - We're working on support for additional vaults/wallets/payment APIs. --- If you’re working on agentic commerce, autonomous checkout, or personal AI shoppers — we’d love your feedback and ideas.

Show HN: JSON Commenter, add comments with valid JSON syntax https://ift.tt/Gx9fZ78

Show HN: JSON Commenter, add comments with valid JSON syntax JSON Commenter is a vscode extension that lets you create inline comments in a JSON file while keeping valid syntax. You create a block with a command that places the comment anywhere legal in the JSON. The text is edited inline and supports word wrap, padding, margins, etc. The comment is in a somewhat good-looking box with minimal extra characters. Zero-width unicode chars give keys that only show two quotes. This is a sample comment block... " ":"----------------------", " ":" This is a comment. ", " ":"----------------------", https://ift.tt/plmXN4R May 27, 2025 at 04:03AM

Show HN: CodeNow – CoderPad over WebRTC and WASM I was doing a lot of Leetcode this winter, and got the idea of building something like it that used wasm in the browser rather than having to manage the complexity of executing remote code securely on a server. Once I figured that out, I thought it would be neat to make it collaborative, like Coderpad — that part was a bit tougher, but it mostly works now, using WebRTC. I'm not sure whether other people will think this is cool, but I had fun building it and learning more about wasm + WebRTC. https://ift.tt/wGRrpzv May 27, 2025 at 02:08AM

Show HN: Tincture – A Color-Matching Puzzle Game I Vibe-Coded with AI in 4 Hours https://ift.tt/xKL73Cs

Show HN: Tincture – A Color-Matching Puzzle Game I Vibe-Coded with AI in 4 Hours Hi, Eight years ago, I had an idea for a color-matching puzzle game. I taught myself Swift and Xcode, spent months building an MVP… and then abandoned it. Last week, I decided to revisit the concept to see how far AI coding tools have come. So I played around with an assistant, and vibe-coded a playable version in about 4 hours. It’s called Tincture. It’s a calm, minimalist puzzle game. There are no timers, or ads, just a grid of colors and some simple rules that prioritize efficiency and pattern retention. What began as a random thought, turned into something that’s actually pretty satisfying to play. Turns out you can use math (modular arithmetic) to optimize the solution of the basic mechanics, so I added some complexity in later levels. I followed what felt fun and used a free AI-powered IDE to reach an MVP that would've taken me MUCH longer to dust off my Swift version or start from scratch learning JavaScript. I’d love your thoughts: • Is the core mechanic intuitive? • Did it hit a “this is kinda fun” moment? • Is it worth polishing further, or should it stay a weird little side project? Thanks for taking a look! https://ift.tt/ghvTR7U May 26, 2025 at 02:26AM

Show HN: 1min Workouts for People Who Sit All Day I am a software developer and in the last few months after recently becoming a father I was barely finding time for a proper workout. Recently I was reading about new research on Snack Exercises and how beneficial mini workouts of less than 2mins every so often, during the day are to our body. So, I decided to build an iOS App for me and others to help with this. The app generates a list of exercises that I need to tick to complete daily or loose my streak. The algorithm takes into account muscle groups and balancing the exercises to hit most main muscles. I also stayed going through all exercises and adding a couple of alternative exercises in case I don't feel like the recommended exercise. Since I'm not a trainer I commissioned professional exercise posture video guides and animations by an exercise expert which I attached to each exercise. I uploaded the app on the app store for free and no ads. If this is something that interests you, I want to hear how you balance a long day on your desk vs exercise. https://shortreps.com May 25, 2025 at 02:11AM

Show HN: Can AI Help Designers Ideate Better? We Spent 5 Wks Finding Out https://ift.tt/HG3mfSJ

Show HN: Can AI Help Designers Ideate Better? We Spent 5 Wks Finding Out We set out to answer a simple but deep question: Can AI actually practically help product designers improve during the discovery and ideation phase of the design process? So we spent 5 weeks running an experiment. We mapped every tool we use for discovery: Mobbin, Dribbble, Pinterest, Twitter, Behance We broke down typical design thinking and brainstorming workflows We reviewed every prototyping or idea-capturing tool we’ve used Then we tried building lightweight AI workflows with various LLM tools and frameworks Result: Yes. Used well, AI can significantly improve design thinking — especially for junior/mid-level designers — by offering faster idea generation, design critiques, and creative merges. Out of that research, we built Moonchild: A discovery-stage design ideation tool that: Generates thoughtful UI concepts from minimal prompts Allows asking design questions and getting structured critique Merges styles, flows, and interaction patterns from multiple directions Outputs great Figma-ready screens and UX flows, fast Try it (private beta): https://moonchild.ai Use code 'hackernews' for early access. Would love feedback — especially from product designers, PMs, and UX folks doing early-stage work. May 25, 2025 at 12:36AM

Show HN: Advanced Chunking in JavaScript/TypeScript with Chonkie https://ift.tt/labBS0s

Show HN: Advanced Chunking in JavaScript/TypeScript with Chonkie Hi HN, We’re Shreyash and Bhavnick. We built Chonkie, an open-source library for advanced chunking and embedding of text and code. It was previously Python-only, but we just released a TypeScript version: https://ift.tt/2fhaCnQ Many AI projects in JS/TS (like those using Vercel's AI SDK or Mastra) rely on basic text splitters. But better chunking = better retrieval = better performance. That’s what Chonkie is built for. Current native chunkers (in TS): - Code Chunker – handles Python, TypeScript, etc. - Recursive Chunker – rule-based, hierarchical splitting - Token Chunker – split by token count (fully customizable) - Sentence Chunker – split on sentence boundaries. Delimiters are customizable, so it works for multiple languages. All chunkers support custom tokenizers, chunk overlap, delimiters, and more. Coming soon in native TS (already available via the API client): - Semantic Chunker – splits texts wherever it detects a shift in meaning. - SDPM Chunker – merges semantically similar disjoint chunks - Late Chunker – generates context-aware embeddings for each chunk - Slumber Chunker – LLM-refined recursive chunks. Significantly reduces token usage (and thus cost) while maximizing chunk quality. - Embeddings Refinery - Embed chunks with any embedding model - Overlap Refinery – Create overlaps between consecutive chunks for better context preservation. Chonkie is free, open-source, and MIT licensed. GitHub: https://ift.tt/2fhaCnQ We’d love your feedback, ideas, or contributions. Thanks! May 24, 2025 at 01:33AM

Show HN: hcker.news – an ergonomic, timeline-based Hacker News front page Hi folks, I've built an alternative Hacker News front page. It is inspired by and meant to be a replacement for hckrnews.com. I built this because HN is woefully underfeatured, but most sites that try to improve it seem to assume that the visual design is the problem. hcker.news tries to maintain HN's familiarity while adding useful enhancements. There are three primary views: - Timeline View: Browse top stories by votes or comments grouped by day, week, or month (e.g., top 20 per day, top 100 per week). - Aggregate View: See top stories by votes or comments over custom time ranges. - Front Page View: The original HN front page, untouched. Feed Filtering: - Custom Keyword Filters: Include/exclude keywords (e.g., include "Rust," exclude "DOGE") or set a minimum score threshold. - No HN Algorithm: Timeline and Aggregate Views show stories usually downranked by the HN algo (e.g., flagged posts or those with too many comments). UI: - Unread Flags: Quickly spot new stories or ones you haven't seen. - Two Layouts: Classic HN style or a compact story view inspired by hckrnews.com. - Multi-column & High-density Modes: Fit more content on screen. - Themes: Light, Dark, and Manila. I'd love your feedback and suggestions. Cheers! https://hcker.news May 24, 2025 at 12:14AM

Show HN: Free Text-to-Video for Learning Anything(Inspired by 3Blue1Brown) https://ift.tt/6KsD4L9

Show HN: Free Text-to-Video for Learning Anything(Inspired by 3Blue1Brown) I'm a huge fan of 3B1B and how he creates appealing and easy-to-understand videos. But he doesn't have a video for every single topic. Whenever I needed help in math or physics, I would try to watch his videos but the issue is that are just not specific enough to my content or curriculum. This issue applies to every single video explanation out there, they just aren't personalized. Most educational videos explain general topics, but they don’t align perfectly with the specific question I have or the way I need it explained. That’s the gap I wanted to fill. So I built a tool that generates high-quality, visually engaging explainer videos that are tailored exactly to the question you ask. Whether it's a niche math problem, a concept from your physics class, or something your textbook didn't explain well, this tool creates a custom explanation in the style of channels like 3B1B, but made just for you. The tool is free to use for some time. Me and my cofounder have dedicated a portion of our savings to this project and unless we get external funding in the near future, we would have to add a paid tier for the product or completely shut it down. Also, would love it if you show some support at our discord server. Thanks for your time! The tool is free to use for some time.

Show HN: Super (YC W18) - Turn company data into answers & agents for your team https://ift.tt/Xjg6dWs

Show HN: Super (YC W18) - Turn company data into answers & agents for your team Hey there, Chris here We're known for our straightforward yet powerful Knowledge Base, Slite(YCW18).We launched our AI-powered search in Feb 2023 and after getting great response and usage, we dove deeper into solving the challenge of knowledge retrieval in daily work. That's why we're now launching our second major product, Super( https://www.super.work ). Super seamlessly connects your existing tools, providing accurate answers, streamlined workflows, automated digests, and much more. You might wonder: Why not just link your apps together using something like an MCP? The problem is that MCPs can't handle complex knowledge retrieval effectively. MCPs are basically LLMs equipped with API toolbelts. If you've ever tried asking a complicated question through an MCP, one that needs data from multiple different tools, you've likely faced frustrating delays. MCPs slowly make API calls one after another, causing long waits while they collect data from each endpoint. By contrast, Super quickly searches through all the data that actually matters from all of your tools simultaneously. This means you'll get your accurate answer in seconds, not minutes. The limitations of MCP-based solutions become clear when you try to deploy them reliably within a team. They either won't index your critical content effectively, won't do it fast enough, or won't cover all your tools at once. Properly chunking, embedding, querying, and filtering data from various sources is still essential. MCPs triggering APIs can't match this integrated approach for speed and accuracy. Moreover, Super understands the value of running multiple tasks simultaneously through LLMs. For example, one step may involve identifying search filters, while another simultaneously uses an LLM to aggregate and refine information. This parallel process quickly shapes the final, accurate answer for users. Additionally, MCPs aren't designed for enterprise-grade use. Businesses need standardized experiences, fine-grained user permissions, and consistent access controls across multiple tools. Super addresses these requirements by indexing data beforehand while still respecting each user's access permissions. Super offers: - Perplexity-like search experience on your team data - A growing selection of integrations with popular data sources - Customizable AI assistants tailored to your specific needs - An extension to embed Super directly into external websites you're already using - A clear path for your company to adopt AI strategically, rather than letting individual employees scatter across different, incompatible tools. And of course... It does comes with its MCP, which makes your agentic workflows actually able to properly tap on your data. Here's a quick video showing Super in action: https://www.youtube.com/watch?v=L5A6BRW90K4 Have you hit such walls with standard MCPs? Have you try building your own solutions? https://super.work May 21, 2025 at 07:48PM

Show HN: Python Simulator of David Deutsch’s "Constructor Theory of Time" Hi HN, I turned the freshly published paper “The Constructor Theory of Time” by David Deutsch and Chiara Marletto (arXiv, 13 May 2025) into an executable Python library. What you’ll find • One-to-one translation of the paper’s formalism: Substrates, Attributes, Tasks, Constructors, and task-algebra operators • Possibility / impossibility predicates and counterfactuals encoded exactly as defined • Test suite that mirrors every lemma and example (>95 % coverage, mypy-typed) • Reproductions of key results: time-keeping substrates, irreversibility proofs, quantum branching tasks, and a self-replicating constructor Why share? Reading the paper is tough going; expressing each definition in code clarified the ideas and surfaced a couple of questions for discussion. Hoping it helps others and sparks extensions. Looking for feedback: • Did I miss any subtleties in the formalism? • Which additional theorems or examples would you like implemented next?

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless https://ift.tt/NhGMuOz

Show HN: Solidis – Tiny TS Redis client, no deps, for serverless Hey everyone! Over the past two years I threw myself back into full-time engineering with a simple goal: write code that gives back to the community. After a lot of late-night FOMO (“AI will do it all for us, right?”) and some painful production incidents, I finally turned my weekend project into an open-source library. [ What is Solidis ? ] - Super-light (< 30 KB) RESP2/RESP3 client with zero runtime deps and first-class ESM/CJS support. - Fully tree-shakable – import only the commands you need. - Written with SOLID principles & full TypeScript typings for every command. - Designed for cold-start sensitive serverless platforms (small bundle + tiny memory footprint). [ Why I built it ] 1. node-redis & ioredis pain - ESM is still an after-thought. - Hidden deadlocks on RST, vague error surfaces. - Everything gets bundled, even commands you’ll never call. 2. I refuse to add a dependency I don’t fully understand – I literally read candidates 10× before `npm i`. 3. Serverless bills love to remind me that every KB and millisecond matters. [ Key features ] - Protocols: RESP2 and RESP3 (auto-negotiation) - Bundle size: `<30 KB` (core) / `<105 KB` (full) - Dependencies: 0 - Extensibility: Drop-in command plugins, custom transactions - Reliability: Auto-reconnect, per-command timeouts, type-checked replies [ Roadmap / Help wanted ] - Benchmarks against `node-redis` & `ioredis` (PRs welcome!) - More first-class Valkey love - Fuzz-testing the parser - Docs site – the README came first; I’d love help polishing full docs This might be my last big OSS push for a while, so stars, issues, and PRs mean the world . If Solidis saves you some cold-start time or just scratches a TypeScript itch, let me know! Repo: https://github.com/vcms-io/solidis License: MIT Thanks for reading, and happy hacking!

Show HN: Easel – Code multiplayer games like singleplayer https://ift.tt/uboGBSV

Show HN: Easel – Code multiplayer games like singleplayer For the past 3 years, I've been creating a new 2D game programming language where the multiplayer is completely automatic. The idea is that someone who doesn't even know what a "remote procedure call" is can make a multiplayer game by just setting `maxHumanPlayers=5` and it "just works". The trick is the whole game simulation, including all the concurrent threads, can be executed deterministically and snapshotted for rollback netcode. Normally when coding multiplayer you have to worry about following "the rules of multiplayer" like avoiding non-determinism, or not modifying entities your client has no authority over, but all that is just way too hard for someone who just wants to get straight into making games. So my idea was that if we put multiplayer into the fabric of the programming language, below all of your code, we can make the entire language multiplayer-safe. In Easel the entire world is hermetically sealed - there is nothing you can do to break multiplayer, which means it suits someone who just wants to make games and not learn all about networking. I've had people make multiplayer games on their first day of coding with Easel because you basically cannot go wrong. There were so many other interesting things that went into this project. It's written in Rust and compiled to WebAssembly because I think that the zero-download nature of the web is a better way of getting many people together into multiplayer games. The networking is done by relaying peer-to-peer connections through Cloudflare Calls, which means Cloudflare collates the messages and reduces the bandwidth requirements for the clients so games can have more players. I also took inspiration from my experience React when creating this language, here's how you would make a ship change color from green to red as it loses health: `with Health { ImageSprite(@ship.svg, color=(Health / MaxHealth).BlendHue(#ff6600, #66ff00)) }` There is a lot of hidden magic that makes the code snippet above work - it creates a async coroutine that loops each time Health sends a signal, and the ImageSprite has an implicit ID assigned by the compiler so it knows which one to update each time around the loop. All of this lets you work at a higher level of abstraction and, in my opinion, make code that is easier to understand. Speaking of async coroutines, my belief is that they don't get used enough in other game engines because their lifetimes are not tied to anything - you have this danger where they can outlive their entities and crash your game. In Easel each async task lives and dies with its entity, which is why we call them behaviors. Clear lifetime semantics makes it safe to use async tasks everywhere in Easel, which is why Easel games often consist of thousands of concurrently-executing behaviors. In my opinion, this untangles your code and makes it easier to understand. That's just the beginning, there is even more to talk about, it has been a long journey these past 3 years, but I will stop there for now! I hope that, even for those people who don't care about the multiplayer capabilities of Easel, they just find it an interesting proposal of how a next-generation game programming language could work. The Editor runs in your web browser and is free to play around with, so I would love to see more people try out making some games!

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser https://ift.tt/lYa87WB

Show HN: AsianMOM – WebGPU Vision-LLM app that roasts you like ur mom in-browser Randomly got inspired yesterday seeing SmolVLM working on WebGPU and had the silly idea for this project. it's not perfect and super limited because of the current limitations of WebML (and admittedly, because I suck at prompting, but that's why it's Open Source haha) but it is 1.5B WORTH OF AI (SmolVLM 500M and LLama 3.2 1B) working RIGHT IN YOUR BROWSER with you not having to install anything! In fact, the whole thing is actually just an index.html that you can install and even use directly! It might be a little bit slow on first try (takes about 3 mins) when it installs models, but it caches it so it's way faster the second time (also, it's available offline after it's cached haha) Works on any modern web browser It may be a funny little project, but it's genuinely taught me so much about WebML and Vision models, and the technologies we're getting with WebML will 100% democratize AI access and make it way simpler and easier to be used everywhere :p GH Repo in case you're interested: https://ift.tt/ICPamkE https://ift.tt/DzHZnWV May 16, 2025 at 12:50AM

Show HN: Family Folder – Help your family remember everything, organise anything https://ift.tt/jVUuHAY

Show HN: Family Folder – Help your family remember everything, organise anything Hi Show HN, I’m both nervous and excited to share what I’ve been working on in the early mornings and late evenings over the past few months: Family Folder – a tool to help you and your loved ones stay connected, simplify planning, and never miss a moment. This is mostly a solo project—though I’ve leaned on ChatGPT and Upwork when I hit the limits of my technical skills. I love learning, and this has been a crash course in programming, DevOps, design, UX, and everything in between. The idea came directly from my own experience: trying to keep on top of family life, from newborns to supporting my mum’s memory, birthdays, childcare logistics, and where the insurance documents are stored. Existing tools felt too generic, too corporate, or too messy. I wanted something built for families. Stack: • Ruby on Rails 7 (via Jumpstart Pro) • PostgreSQL • Hosted on Heroku (EU region) • S3 (EU) for file uploads • (Coming soon: iOS app & AI assistant) Family Folder is private by design—you only see what you’re invited to. It’s meant to be simple enough for parents or siblings to actually use, but structured enough to avoid chaos. If this sounds useful—or if you’ve ever tried to manage a family using group chats or shared docs—I’d love your feedback. What would make something like this truly work for your family? Thanks for taking a look! – Tony https://ift.tt/Z9MoIAn https://ift.tt/Z9MoIAn May 15, 2025 at 12:27AM

Show HN: Build a free linktree alternative that skips in-app-browsers https://ift.tt/fPVZDTW

Show HN: Build a free linktree alternative that skips in-app-browsers I searched for something like this and couldn’t find it. I thought, this can’t be that hard, so I built it myself. What really messed me up was that social media apps open websites inside their in-app browsers… It costs nothing to run, so it’s free for everyone. You only need to sign up if you want to create your own link page. If you just want to convert your existing link into one that automatically skips the in-app browser, you can do that without an account. I used Next.js and MongoDB. And I’m proud to say: Not Vibe-Coded! Let me know if you need help or have questions. https://ift.tt/ODBVnk4 May 14, 2025 at 11:18PM

Show HN: Doxxer – CLI tool for dynamic SemVer versioning using tags https://ift.tt/hufrVjb

Show HN: Doxxer – CLI tool for dynamic SemVer versioning using tags Hi, first time poster here! Wanted to share a small CLI utility in Rust: doxxer! It is a tool for working with Git repositories, more specifically, extracting and calculating current/upcoming semantic versions for your repo's tags. It is heavily inspired by the output from "git describe --tags". Why use anything else then? The output is not fully SemVer compliant and therefore I was modifying it in all my projects separately, which I wanted to avoid. Single binary, single predictable output. It does not currently have pre-built binaries, so you have to install it via cargo, but it's in the roadmap! https://ift.tt/2qmGTbY May 14, 2025 at 08:40PM

Show HN: GS-Base – A multifunctional database tool with Python integration https://ift.tt/yHgkdSG

Show HN: GS-Base – A multifunctional database tool with Python integration A wide range of possible use: from simple contact/inventory lists, photo albums to editing CSV/text files and processing (transforming, splitting, merging, normalizing) large, multi-GB data tables in various file formats. Text, Numeric, Long Text / Memo fields, Image / File fields; Code fields for code snippets with syntax highlighting for 16 programming languages. You can analyze, query and consolidate data, generate pivot tables, perform calculations, merges and joins with up to 256 million rows, 16K columns and 4GB+ files efficiently using even older PC's. Several filtering methods, searching for duplicates, for unique values and their frequencies, search-as-you-type, random and quartile searches, full-text searches, fuzzy searches. RegEx filtering of millions of records in seconds regardless of the number of the returned found records. Searching for file duplicates, finding similar photos/images, music and video files using any EXIF tags and multimedia (e.g. mp3/mp4) tags. Playing filtered lists of mp3's. Very fast data consolidation - you don't have to bother with permanent indices; internal indexes are created automatically whenever aggregation and binary lookup functions need them. Generating disk/folder listings and monitoring all file changes with searchable history of modifications. Mass-renaming, -copying and -deleting files based on filtered file listings. GS-Base can be installed on any portable storage device and used without performing any registry modifications. Fully offline - doesn't need internet connection. To move it to another computer you can simply copy the installation folder containing a few files. Questions and suggestions are welcome. https://ift.tt/dF9nNDa May 13, 2025 at 02:32AM

Show HN: Lumoar – Free SOC 2 tool for SaaS startups https://ift.tt/HErYJUv

Show HN: Lumoar – Free SOC 2 tool for SaaS startups We built Lumoar to help small SaaS teams get SOC 2-ready without paying thousands for Big 4 consultants or dealing with bloated compliance platforms. As a startup ourselves, we faced the usual issues: long security questionnaires, confusing audit requirements, and expensive tools that felt overkill. Lumoar is a simpler alternative: - Generate compliant SOC 2 policies automatically - Track your controls and progress in a clean dashboard - Upload evidence and get plain-language recommendations - Designed for engineers and founders, not compliance pros It's free to start — you can generate policies and explore the dashboard without a sales call or demo. Would love to hear what blockers you’ve faced with SOC 2 and what other frameworks you’re thinking about (e.g., ISO 27001, GDPR). All feedback is welcome. https://www.lumoar.com May 13, 2025 at 12:35AM

Show HN: AI-powered batch photo editor for real estate photographers https://ift.tt/kTPVgS7

Show HN: AI-powered batch photo editor for real estate photographers I got tired of repetitive editing tasks, so I built a tool that simplifies bulk edits using text prompts and AI workflows. Now I can quickly handle things like virtual staging, changing backgrounds, adding/removing objects, adjusting brightness and exposure, color corrections, boosting contrast and clarity, fixing distortions, batch color grading and much more! But most importantly, I can do this to all selected images, tens, hundreds or more. I'm particularly interested in feedback on the workflow and UI from photographers/editors who handle large volumes of images. I've increased the free plan credits to 40 so you can edit up to 40 images, if you'd like to help me trial it out. Otherwise I'm happy to answer any questions about the implementation or roadmap. https://4ditor.com/ May 9, 2025 at 06:38AM

Show HN: Hackergrep.com – search Hacker News for tech jobs https://ift.tt/BAeZ3C4

Show HN: Hackergrep.com – search Hacker News for tech jobs Hey HN, I built https://hackergrep.com and I think it's ready for some attention. What is it: I wanted a fast, flexible, and focused job search tool to find new tech jobs and I didn't see anything that really fit my needs, so I built this app because you can just do things. HackerGrep indexes several recent threads on HackerNews and combines the results into a feed matching your desired search filter criteria. The system can send you daily email updates when new search results for your queries are available; opt-in search query emails are sent for 30 days and then automatically stopped. New job alert emails are batched and sent daily, so you'll get one email per alert you configure until you unsubscribe or the 30 days are up. Key features: > no banner ads / clutter. > it's free to use. > no accounts/logins needed. > advanced search syntax and full-text search. > can notify you about new jobs matching your queries via email. > the search and alert emails always show the most recent results first. (To report bugs, suggest parser/logic improvements, offer me a job, or just say hi, etc, you can find my contact info on the https://ift.tt/U9InYh8 page) You can try it from any web browser. It's optimized for desktops or tablets with a reasonable screen size but should function anywhere. https://hackergrep.com https://hackergrep.com May 10, 2025 at 11:42PM

Show HN: PLAttice, for assembling structures much larger than the 3D printer bed Struts, nodes, and pins are reversibly assembled into fully 3D printed lattices, trusses, and tree-like structures spanning up to a few meters.

If you want to give it a try, find the *.stl files at the bottom of the page; figure ~1 kg of PLA and ~1 day of print time per meter of box truss; pay attention to print orientation; plz respect the license; and definitely print the pin trimming jig. https://ift.tt/gP5UXeZ May 11, 2025 at 01:48AM

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions https://ift.tt/6eZKXif

Show HN: Limits.fyi – See what you are getting out of all your AI subscriptions Hey HN, I've personally been having a hard time keeping track of all the changes to AI subscriptions these days. Sama is always tweeting about ChatGPT usage limits being improved as they add more GPUs, nobody knows how many Claude messages you get in a day, and Windsurf just recently updated their pricing plan. It's becoming increasingly difficult to get a clear and transparent view of what you're actually getting with each subscription. This becomes especially frustrating when you run into those annoying “no more remaining message” popups right in the middle of a coding session. I've also noticed many developers suffer from what I've started calling "query anxiety”, this is when a person is always worried about hitting their usage limits, so they just end up not using these models when they actually need them. That's why I created limits.fyi which lets you view and compare usage limits for all the popular AI subscriptions in one place. You can: - See exactly what usage limits come with each plan - Filter by specific models to find which subscriptions give you access - Compare prices to find the best value for your needs - Discover new services you might not have known about I try and keep the data up-to-date, and welcome user submissions. If you notice changes or have new information, you are encouraged to contribute using the submission feature at the bottom of the page. Check it out here: https://www.limits.fyi/ I'd love to hear your thoughts and suggestions on how to make this more useful. https://www.limits.fyi/ May 9, 2025 at 12:08AM

Show HN: Cloi – free local debugging agent in your terminal https://ift.tt/ozT8BJm

Show HN: Cloi – free local debugging agent in your terminal Hey everyone! For the past two weeks my friend and I have been heads-down building Cloi, a fully local debugging agent that runs right in your terminal. You probably know the drill—every AI coding tool asks for API keys, subscriptions, and uploads your entire codebase to the cloud. Cloi does none of that: it runs entirely on your machine, with no cloud, no API keys, no subscriptions, and zero data leaving your system. What Cloi does: - Contextual error capture: Grabs your stack trace, local files, and environment to understand the issue. - Local LLM inference: Spins up Ollama on your box and generates targeted fixes—no external servers. - Safe patch application: Presents you with diffs and only applies changes when you explicitly approve. - Model‐agnostic: Ships with Phi-4 out of the box (surprisingly capable for its size!), but you can swap in any Ollama model you’ve installed. Why we built it: - Maintain full control over your code and data—ideal for security-sensitive projects - Avoid recurring subscription fees and cloud vendor lock-in - Keep your development flow entirely offline when you need it Highlights: We hit 202 stars in just 5 days, which tells us we're not the only ones who wanted this! Cloi is plug-and-play (just install and run), and we designed it to be completely unopinionated, meaning you can you whatever Ollama model you want. Get it now: npm install -g @cloi-ai/cloi If you find Cloi useful, we’d really appreciate a star on GitHub. Try it out, let us know what you think, and happy debugging! — Gabriel Cha & Mingyou Kim https://ift.tt/Rs2lPyh May 7, 2025 at 10:55PM
